SACK-HOLDING DEVICE.

Specification of Letters Patent.

Patented Mar. 17, 1914.

Application filed June 25. 1912. Serial No. 705.883.

To all whom it may concern Be it known that I, NICHOLAS Manna. citizen ot the United States, residing at Peoria, in the county of Peoria and State 2 of Illinois. have invented certain new and usetul Improvements in Sack-Holding Devices; and I do hereby declare that the 'lollowing is a full. clear, and exact description of the invention, which will enable others skilled in the art to which it appm'tains to make and use the same.

This invention pertains to a sack holding device.

it relates particularly to a device for use holdthe mouth of a sack so that said in mills, food stores and the like for ing open sack may be readily filled.

it relates, also. to a device for supporting and, holding open the mouth oi a sack.

The object of the invention is to provide a simple means t'or holding open the mouth of a sack andv for releasing said sack when 1 tilled. together with means for automatically returning the first said means to its tn-iginal position for receiving another sack. To the end that the invention may be un- 1 derstood l have provided the aectnnpanying drawing, in which:

Figure l is a side elev holding device. Fig. 2 is a front elevation of the same. device in perspective. vice in plan. Fig. 5 is an elevation ot a spike and a Fig. 6 shows a bell-crank-lever in perspective, and Fig. 7 is a cross section of one of the supporting bars of the frame of the device showing the spike in Fig. 5 in con nection therewith.

are two uprights or frame members as the supporting parts o l the device which for convenience may be mounted upon a suitable support, in this instance and merely for illustration the platform of a weighing scale A by means of members l) for example. The vertical. extension of said member D is secured to the meml'ier C by means of bolts F for example. it being understood, of course, that one of these members is provided for each said up.

right C.

At the top of each upright C and secured thereto near one end is a horizontally disposed bar G so placed as to extend forward to overhang the member upon which ation of my sack Fig. 23 shows a portion of the I Fig. 4t. shows the deholding device for the samem sack holding l l the members (l are mounted. A diagonally disposed brace H is secured at its endsto said bars (t and the uprights as clearly shown. so as to lend stillness and strength to the structure. As an additional strengthening means. and as a support also for parts to be described presently, plates J are secured to the inner sides oi the members G and the said uprights.

l lxtending through the rear ends of the bars G is a .bolt K, Fig. 3. upon which is carried a piece of tubing l for spacing the two bars (1 apart. Below the bolt K and extending through the plates J just described is a rock shaft M preferably threaded at its nds to receive a pair of nuts N 0 shown in Fig. 3. there being but: one of the i sets of nuts shown. Placed upon the shat't between the two nuts N O is a bell-cranklever l constructed for instance of sheet metal. or it may be a casting. As shown in Fig. (3. one corner of the lever is provided, for convenience, and as a good means of tiring the lever relative. to the rock-shaft, with an ear Q at two of its edges which are bent over into planes perpcmlicular to the l plane oi the lever to engage the sides of y the nut N, as shown in said Fig. The two a l l nuts are adjusted on the threads to clamp the lever firmly between them and as to lock one another so that they cannot loosen.

The lower corner of the lever, as arranged 1 in Fig. 3, has pivoted thereto one endv of a rod R whose other end is pivoted to the lower corner of a lever S at the front of the i device which lever is pivoted in any good manner to the plate J and is provided with i a handle T. It is understood that substany tially the same structure is provided at the l other side of the apparatus, see Fig. 2. lnnnediatcly above the forward free ends of l the levers P and S the bars G are provided with vertical bores U each of which is l preferably titted with a tube V. Fig. 7. Slidable in each tube is a spike 7 whose 5 lower end is suitably carried in any form of tilting pivotally attached to the said levers I S. I have indicated in Fig. 5, as one of 1 the means of: carrying these spikes, a sheet I metal member 2. This takes the general form shown in Fig. 3 being provided in its top with a hole 8, Fig. 5, through which the spike extends. In this particul-ar in- 1 stance the spike is provided with a head 4 t has two downwardly extending ends 5 between which is held the lever or plate S, or P.

A spring 6 is wound around the rock shaft M, Fig. 3, one end being secured in some part of the device as for instance in the plate J to which it is adjacent, while the other end is secured in the rock shaft as for instance by extending it through the same. The tendency of the spring is to maintain the parts in the position shown in Fig. 3 with the spikes IV projecting above the upper surfaces of the bars in position to receive the sack. In securing the sack in place to be filled its edges are hooked upon the four spikes IV in such a position that its mouth is spread very wide so that the contents of a scoop or shovel may be readily placed in it. When the proper weight is shown, or when it is desired to remove the sack the lever T of the lever S is depressed and this action causes all the spikes to be simultaneously drawn downward into the tubes V so that the sack is at once released, the spring V returning the spikes to their normal or eX tended position ready for the reception of another sack.

It will be understood that by the arrange-- ment described as to the nuts N O of the rock shaft M, that both of the levers P, i. e. at opposite sides, will be operated simultaneously.

I desire to state that I do not confine my self to the exact arrangement as to details shown and described since changes may be made that will lie within the meaning of the I invention but it may be seen that the device is simple and effective and will hold a sack while being filled and whose contents may be weighed while being filled thus saving considerable annoyance.

My device is distinguished from others of its class by its simplicity of structure and few parts and in the details of its construction.

Having described my invention, I claim:

1. In a sack holding device, in combination, a frame having an open side to receive a sack, a rock shaft extending between two of the frame portions at the back, a bellcrank-lever at each end of said shaft, a pair of bell-orank-levers pivoted to the frame, one at each side, and spaced from those of the shaft, a link connecting each bell-cranklever of the pair with one of the levers of the shaft, and a member carried by each of the said levers adapted to hold the edges of the sack.

2. In a sack holding device, in combination, a frame having an open side to receive a sack, a rock-shaft extending between two of the frame portions at the back, a bellcrank-lever at each end of said shaft, a pair of bell-crank-levers pivoted to the frame, one at each side, and spaced from those of the siaft, a link connecting one of the bellcrank-levers of the pair with one of the levers of the shaft, a member carried by each lever adapted to hold the edges of the sack, and means to resiliently hold all the memhere in position to receive the sack.

In testimony whereof I afliX my signature, in presence oftwo witnesses.
